Adaptive Defrost
Adaptive Defrost can be described as a defrost system that adapts to a refrigerator’s surrounding environment and household usage. #31-9062 for more information on Adaptive Defrost. It reduces the length of time between defrosts by 300 seconds (multiplication factor) for each second that each door is open (if both doors are open. The thermostat opens when the evaporator temperature raises to 60 °F and closes when the evaporator temperature lowers to 45 °F. Adaptive Defrost (Pre-Chill Operation) When the main control board determines that defrost is necessary. the evaporator will be totally clear of any moisture. the fresh food temperature will be regulated by the evaporator fan running at low speed. prior to the cooling operation. the compressor run time between defrosts will be reduced to as little as 8 hours. These models do have an 8-hour defrost holdoff. the main control board turns off the compressor. the main control board will terminate defrost heater operation. the freezer temperature may be driven below the set point. electronic control to determine when the defrost cycle is necessary. the main control board monitors the following refrigerator operations: are opened frequently and/or for long periods of time. the compressor.

Normal Operating Characteristics •
• • Evaporator fan running, without compressor or condenser fan. Liner Protection Mode, fan comes on when the doors are open for 3 minutes. Different sound levels can be heard when the fan changes speed; however, the fan should never be heard oscillating between speeds. Response time for drastic temperature change is 2 to 10 minutes. The main control board will only respond to 8 °F of temperature change per minute as determined by resistance of sensor.

Liner Protection Mode
The liner protection mode will activate if either of the doors has been open for 3 minutes. This mode will start the evaporator fan on high speed. This mode is controlled by 2 timers. Timer #1 monitors door-open time. A 3-minute door-open count begins when the door is opened. If 3 minutes elapse before the door is closed, the liner protection mode will become active. Once the door is closed, timer #1 resets and liner protection mode goes into standby. In standby, normal fan and damper operations resume and timer #2 begins a 3-minute door-closed count. If 3 minutes elapse without a door opening, liner protection mode will completely deactivate. If a door is opened within the timer #2 door-closed count, the remaining time in the door-closed count will be deducted from the timer #1 door-open count.

Evaporator Thermistor
The evaporator thermistor is mounted on the upper left side of the evaporator. The defrost cycle will terminate when the main control board detects 38 °F from the evaporator thermistor. The main control board must sense 38 °F in less than 35 minutes, or the defrost cycle will time out. Average time to defrost is less than 16 minutes. Defrost time should not exceed 35 minutes. Defrost time does not include dwell period.

Defrost Overtemperature Thermodisc
The defrost overtemperature thermodisc (bimetal switch) is mounted on the evaporator and provides overtemperature protection during defrost. This thermostat will open at 60 °F and will close at 45 °F. Note: The main control board will not know if the heater does not come on due to a broken heater, open defrost overtemperature thermodisc, or open wiring harness. The defrost heater is controlled by maximum time on the main control board or temperature at the evaporator thermistor.
